    Default Anyone find a successful 3 blade prop for a stock stiletto?

    Anyone have luck with a 3-blade prop on a stock stiletto? If so, which one? Thanks in advance!

    I gave a 440/3 a go for awhile... Seemed to work OK. Not particularly fast, but that was early on and I hadn't gotten the setup to where it is now, so it may be worth exploring again...

    Hi Darin,
    I really like the carbon props. Do you think this one will work well? Thanks in advance!

    No, I really don't think they will work well... 1) They have too much blade flex to be consistent, and you need to be able to rely on the power delivery in a tunnel to keep it balanced in the turns. 2) The tend to not have enough cup in the blades, and slip too much as a result...

    These types of props generally seem to be aimed at hydro applications, with their higher lift characteristics.

    I'd start with an X440/3 or X442/3 and start tweaking on that... Or MAYBE an X537/3 if you are going to run a UL-1 setup. You'll need to bend on any of them to make them work correctly, but that's generally the case with any prop.

    I saw that... I don't have an extra 440/3 I can part with... (I don't get rid of many props... takes too long to prep, and they have too many uses! )

    You might also give this Grim prop a try, as I think it's the same thing, and this one should come fairly RTR...

    This would make a good foundation for tinkering as well...
